If Your Name Is Tracy Peterson, Be Worried

This story is so amazing and has so many nuances that I don't think I can explain it in a clever story fashion. I'm just going to run down the facts of the case.

23 year old Stacy Peterson is missing.


Two days before she went missing she told her aunt that she wanted a divorce from her husband.
She also told her sister than she feared for her life.
She is married to 53 year old Drew Peterson. They recently celebrated their 4th anniversary, meaning they got married when she was 19.
Drew is a Sergeant in the Bolingbrook, Illinois Police Department.
He told cops that Stacy called him Sunday night to say she was leaving and he thinks she ran away with another man.
Relatives said she was supposed to meet them Sunday but never did.
Her cell phone has not been used since Sunday night.
The couple has two kids, a 4-year old son named Anthony and a 2-year old daughter named Lacy. I'm not making that up.
Peterson has two sons from his previous marriage, Stacy is his 4th wife.
And speaking of marriage number 3, that wife, Kathleen Savio was found dead in her bathtub in 2004.
Peterson was bringing the sons back to Savio's house after a weekend visit but she didn't answer the door. When the finally got in the house she was dead in the tub.
Coroner's report ruled that she drowned, because her fingers showed pruning. But the tub was dry.
Peterson collected about $600,000 from life insurance policies and asset sales after her death.
If the worst is true, this guy killed his wife, married a girl 30 years younger, had a daughter, named her Lacy Peterson, knowing full well about the other Laci Peterson, then killed this wife too.
